Which is not a lobe of the cerebrum?
A. Parietal lobe.
B. Insula.
C. Occipital lobe.
D. Temporal lobe.
E. Sphenoidal lobe.
Answer: E. Sphenoidal lobe.
The cerebrum, the largest part of the brain, is divided into four main lobes: Other areas are also affected and they include the Frontal, Parietal, Occipital, and Temporal areas. About the mentioned three lobes: The parietal, occipital, and temporal all of these areas can be at least considered as clearly marked and in the common language deemed as lobes of the cerebrum. This is not a lobe, but it is a small region that is partly in the cerebral cortex that is in the lateral sulcus part. However, there is no hierarchy in the list of the officially recognized lobes of the cerebrum specifically outlining the sphenoidal lobe. Hence, the option “Sphenoidal lobe” cannot be used to point at any of the actual lobes that are the constituents of the cerebral part of the brain.
